LIQUID-BISPENSING DEVICE.

Application led august 2, 1922. Serial No. 579,088.

T 0 all whom t may concern.'

Be it known that I, ANDREW D. lVYCKoFr, a citizen of the United States, and a resident of Oak Park, county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid-Dispensing Devices, of which the following is declared to be a full, clear, and exact description.

This invention relates to liquid dispensing devices and its principal object is protection of the device against the inelemencies of the Weather. The invention has especial ap plication to oil tanks, such as are in common use at garages and iilling stations. As is well known, oil tanks are provided with pumps for withdrawing and dispensing the oil, and a great deal of annoyance and loss of oil is occasioned, because the oil continues to drip from the discharge nozzle, after the measure or container into which the oil is delivered, has been removed from beneath the nozzle. Various devices have been designed to catch the dripping oil and return it to the tank, but these are at best unsatisfactory, or impracticable, and liable to get out of repair, and are otherwise objectionable. Rain is apt to enter the oil return devices, or dust and dirt, or other foreign particles are apt to enter the tank through the return tube. Moreover, when springs are employed for automatically returning the drip tube to a position in which it catches the dripping oil, snow or ice is apt to gather on the spring and interfere with the operation of the evice. l

'With the use of a dispensing device embodying the present invention, these objectionable features are eliminated. The invention consists in the several novel features, hereinafter fully set forth and claimed.

The invention is clearly illustrated in the accompanying drawing, in which:

Fig. 1 is a side elevation, partly broken out, of a liquid dispensing device, embodying a simple form of the present invention; Fig. 2 is a plan thereof partly broken away; Fig. 3 is a fragmentary side elevation of the discharge nozzle and return tube; Fig. 4 is a detail, vertical, cross section, taken on line 4 4 of Figure 1; Fig. 5 is a detail, horizontal section, taken on line 5--5 of Fig. 1; and Fig. 6 is a perspective view of a fragment of the drip tube.

Referring to said drawing, which illustrates one embodiment of the present invention, the reference character 7 designates a fragment of an oil tank, and 8, the base of an oil pump 9, which is mounted on the tank and has an arm 10, terminating in a nozzle 11, through which the oil is discharged rlJhe pump 9 and discharge arm 10 are of conventional form, but the nozzle 11 contains novel features forming part of the present invention. Below thernozzle is mouth 12 vof the drip tube 13, which leads to a return pipe 14 thatis secured in'the base 8 and discharges into the tank. .The drip tube 13 1s swiveled, or rotatively mounted upon the return pipe 14, whereby it may be swung from a position, with its mouth under the discharge ,orilice of the nozzle 11, to a position in which it does not obstruct rthe flow of oil from the nozzle into a measure or other container' placed below the nozzle. In the form of the invention illustrated, the drip tube 13 inclines downwardly from its mouth 12, and has a pipe 15 on its lower end, which protrudes into the return pipe 14. The upper end of said return pipe 14, is held in a hollow boss or lug 16, which projects laterally from the pump body, and located in a recess 17l in said boss 16 is a coiled spring 18, which surrounds the pipe 14, and engages atone end with the boss, and at the other end with the drip tube, the tension of the spring being exerted to turn the drip tube 13 in the direction of the arrow in Fig. 2, andthereby returnV it to effective position below the nozzle, whenever the drip tube is released from any other position. On the lower end of the drip tube 13, is a iiange or cover' 19 which overlies the boss 16, and cornpletely covers the recess and spring, thereby preventing rain, snow, dust or other foreign particles from entering said recess or return pipe 14. To more effectively guard against the entrance of water or other foreign matter, the flange 19'has a down turned annular bead 2() which overhangs an upturned bead 21 on the boss 16.v The flange 19 rests on the return pipe 14 or boss 16, and a pin or stud 22 secured in the pump body above the flange 19 prevents displacement or removal of the drip tube from the return pipe.

The nozzle 11 has a neck portion 24 which is attached to the arm 10, and it has a spout 25, which has a discharge orifice 26 vin its lower end. The mouth 12 of the drip tube 13`flares upwardly as a preference, to a place, when its Vedge 27a is immediately below the discharge orilice 26. One half of its upper edge is free to swung under the spout 254 (see Fig. 4) but one side 2T of the mouth is preferably extended upward beyond said edge so as to stand along sideof the spout, when in the position shown in full lines in the drawing. AExtending over the mouth l2 are semi-circular flanges 28, 29, which are formed on said spout, and completely cover the open mouth 12,the flange 28 is placed close tothe upper edge 27 of the mouth, and has a down turned rim 3U which'surrounds the immediate portion of the 'mouth belowthe edge 27', andthe flange 29 is placed close to the upper edge of the eXtension 27 of the mouth, and as a preference has a down turned rim 31 on its edge. Connecting vthe lflanges 28, 29 are vertical webs 82 that radiate from'the body ofthe spout 25, and Vif desired said webs may have ribs 32 along their outer edges that overlap the upright edges of themouth extension`27. 'It is readily apparent from the above, that rain, snow, sleet,or other foreign substances, are kept out of the drip tube, while the mouth ofthe 'drip tube is held underneath the nozzle. Furthermore, the webs 32 act as a stop against which the spring 18 holds the mouth extension 27, thereby locating the mouth centrally un'der the spout, whereby any oil dripping from theV spout will be carried back into lthe tank. line mesh wire screen may be placed in the passage in the mouth to interrupt large particles. Y

In use the spring 18 yieldingly holds the mouth of the drip tube underneath'the spout of the nozzle as heretofore explained. A person desirng'to draw off a quantity of oil swings the drip tube away from the nozzle, either with his hand or with the measure or container which is to be filled, and holding lthe 'drip tube away from the nozzle with the measure. Such a position of the drip tube is illustrated by the dotted lines in F ig. 2. The pump'is then put into operation and the desired quantity of oil drawn off into the measure. As the measure is removed from beneath'the nozzle, the spring swings the drip tube back beneath the nozzle with the mouth completely covered by the flanges 2S, '29, protected against the entrance of foreign substances1 and in position to catch and convey back to the tank any oil that drips beneath the spout.

vMore or less variation ofthe enact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit `myself to the exactv form of the construction shown and described, but intend, in the following claims, to point out all of the invention disclosed herein.
